Drones are so cheap you can send a full constellation of drones waaaay cheaper than the cost of one sentry tower and it will defeat it. These systems have limited handling capacity. With enough drones you can get through anything.
The main problem is, there are more than enough drones. All I’m saying above is you probably just need 8 of them to get through Andurils system.
Also, the method to defeat such systems is not classified. It’s quite obvious and china can even easily overwhelm carrier defenses using this method.
My only disagreement with your position is that you seem to evaluate it in a void. Compared to other systems out there, is Anduril really that bad? I suspect if you're in a trench you'd much rather have a system that can down "just" 8 drones at a time than one that can down zero.
